Computer Diagnostics
In Simple Terms:
Think of your truck’s computer like the brain of the operation, constantly monitoring everything from the engine to the brakes. If something isn’t quite right, the computer often stores a “trouble code” – like a little digital breadcrumb that tells us where the problem might be.
How do you know you need it?
Your check engine light suddenly pops on. Imagine you’re heading out of Nanaimo, maybe with a trailer in tow, and suddenly that little yellow ‘Check Engine’ light on your dashboard flickers on. Or perhaps your truck just isn’t running as smoothly as it usually does – maybe it’s a bit sluggish on acceleration, or you’ve noticed your fuel economy isn’t what it used to be. These subtle changes, or that not-so-subtle warning light, are your diesel truck’s way of telling you something isn’t quite right under the hood.
Modern diesel engines are complex machines with sophisticated computer systems constantly monitoring their performance. When something deviates from the norm, these systems often trigger a warning. Ignoring these early signs can lead to bigger, more expensive problems down the road.
If you’re experiencing any of these issues, it’s time to let the experts at Four Wheel Truck Repair take a look with our advanced computer diagnostic services.
What you can expect from us:
Computer diagnostics is like having our expert technicians “talk” to your truck’s computer. Using specialized tools and software, we can read those trouble codes and get a snapshot of what’s going on under the hood. Our Red Seal certified technicians, with over 20 years of experience, then use their extensive knowledge to interpret these codes, analyze the data, and pinpoint the root cause of the issue – not just the symptom.
Whether it’s a sensor acting up, an emissions control problem, or something else entirely, our Powerstroke, Cummins, and Duramax specialists (and experts on ALL makes and models) use this technology as the first step in getting your truck back to its optimal performance.

Electrical Diagnostics
In Simple Terms:
Just like the wiring in your house powers the lights and appliances, your truck has a complex electrical system that controls everything from the headlights and power windows to critical engine functions.
How do you know you need it?
Your headlights are flickering, your power windows aren’t working. You’re getting ready for an early haul out of Nanaimo, and you turn the key in your trusty diesel. Instead of that familiar rumble, you hear… nothing. Or maybe your headlights are flickering erratically, making night driving a nerve-wracking experience. Perhaps your power windows are refusing to roll down on a warm day, or your trailer lights are acting up.
These frustrating issues, big or small, can often point to underlying electrical problems in your diesel truck. Modern trucks rely heavily on a complex network of wiring, sensors, and control units. When connections become corroded, wires fray, or components malfunction, it can lead to a cascade of electrical gremlins. Don’t let electrical hiccups leave you stranded or compromise your safety.
If you’re encountering any of these electrical oddities, the skilled technicians at Four Wheel Truck Repair have the specialized tools and knowledge to diagnose and resolve your diesel truck’s electrical issues efficiently.
What you can expect from us:
Electrical diagnostics is like being a detective for your truck’s wiring. Our experienced Red Seal technicians use specialized tools, like multimeters and circuit testers, to trace electrical pathways, check for voltage, identify faulty wiring, blown fuses, or malfunctioning components like alternators, starters, and batteries.
With over two decades of experience, we understand the intricate electrical systems of all makes and models, including the specific nuances of Powerstroke, Cummins, and Duramax trucks. We don’t just guess; we systematically test and diagnose the problem to ensure a reliable and lasting fix, getting all your truck’s electrical systems back in working order.
